That means you get remote trip capability and separate alarm signalling out of the box, no extra modules needed for basic status feedback. Power loss peaks at 162 W at full rated load, which matters for enclosure heat budgeting — if you are packing several of these in a closed panel, the thermal rise adds up. The case dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON or legacy 3WL/3VL cutouts without re-drilling the gland plate. Depth is tight enough for 200 mm shallow enclosures, but leave clearance for the shunt trip wiring and the auxiliary switch harness on the left side. Operating temperature range is -25 °C to 70 °C, with derated current values every 5 °C above 40 °C — at 70 °C ambient you are down to 520 A continuous. ## What the current derating curve tells a panel builder The continuous current rating drops from 630 A at 40 °C to 520 A at 70 °C in 5 °C steps — roughly 2.5 % loss per degree above 40 °C. If your enclosure ambient runs 55 °C, the usable rating is 575 A; at 60 °C it is 557 A. That is the number to use for the load calculation, not the 630 A nameplate.","metaTitle":"Siemens 3VA2463-7HN32-0JH0 SENTRON MCCB, 630 A, 3-Pole, 110","metaDescription":"Siemens 3VA2463-7HN32-0JH0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, line protection.
